i'd seriously reconsider this move. You will NOT get a stake. The network weight is too high. You should take your losses now as the coin is plummeting. I can tell you I've had 700 b3 coins i bought on 9/12 for 10,000sats and they haven't staked yet. If they do before they are worthless i'll be ok. 375 coins staked today is even more dangerous to risk BTC value. Best wishes.
